I have a 1TB EHD that is split into two partitions. Half for my Mac to back up to, the other had been for my wife to back up to. Is there a way to delete her partition, while maintaining my half, so that I have 1TB instead of 500GB? We are finding other backup options for her, and I want to use the entire 1TB for my Mac, but don't want to lose the 1.5 years of Mac backups (499GB) on there. (Also, System Information tells me the "Mac backup" partition has 213GB free of the 500GB, and TM tells me I need 316GB. I also recently upgraded my Mac's HD from 320 to 500. So I now need the full 1TB of backup space.) Specs: 2010 MBP 500GB HD, 8GB ram, 2.4 GHz processor, Mavericks, ummmm... the EHD is a Fantom GreenDrive 1TB eSATA USB 2.0 External Hard Drive. Backup with Time Machine. Used Disk Utility to set it up.
